In mathematics, the Hasse invariant of an algebra is an invariant attached to a Brauer class of algebras over a field. The concept is named after Helmut Hasse. The invariant plays a role in local class field theory. See more Let K be a local field with valuation v and D a K-algebra. We may assume D is a division algebra with centre K of degree n. The valuation v can be extended to D, for example by extending it compatibly to each commutative … See more • Shatz, Stephen S. (1972). Profinite groups, arithmetic, and geometry.

"WebApr 26, 2024 · The theory of Hasse invariants in its modern form goes back to the algebro-geometric pursuit of modular forms modulo p, pioneered by Deligne, Katz, Serre and others in the late 1960s and early 1970s. Since then, many people have studied generalizations and applications of the classical Hasse invariant of an abelian scheme cf. [29, 40, 52]. " - Hasse invariant
